Q

Cause of a positive trendelenburg test

A

Abductor wasting secondary to chronic pain
Superior gluteal nerve injury
Structural - developmental dysplasia of the hip

19
Q

Cause of an ulnar palsy

A

Anatomical compression - cubital tunnel syndrome at elbow - guyons canal syndrome at wrist
Trauma - supracondylar fracture of the humerus - elbow dislocation

20
Q

Ulnar pardox

A

Proximal lesion lead to paralysis of ulnar half of FDP which leads to less wasting

21
Q

Feature of ulnar nerve palsy

A

Partial claw hand - little and ring fingers
